To all whom it may concern:

lie it known that it, Vl anrnn hour, a citizenot Switzerland, and a resident of Pieterlen, ate of Bern, Eiwititer-land, have invented certain new and useful. llinprmcments n Vises, oil which the. i'iollowing is a s iccilication.

This invention relates to an inlprovemcnt in vises. a

One of the principal objects of the lumen-- tion is to 1:)I"()'Vlldell]j1 iuiiproved vise which is quick acting in that the ja s maybe easily and quickly adjusted to th proximate positions without neccssi ty rotating the main o 'iera-ting screw while at thesame time not impairing the eitlectivenea-is of this screw when it is brought into action.

Another object is to provide a vise of this character which is of strong and durable construction and capable not exerting; a powerful gripping action so as to hold the worker stock whichit engages in proper position.

iltnother object is to provide a vise of this character which may be conveniently and readily inanutactured, which may be easily taken [lOWIlfOF purposes; oi replacement or repair and which is comparatively incrpein sivo to produce d Other ob ects and advantages of the 1n vention reside in Ct-BFlLllliIlOVEl features oil construction, combination and arrangement of parts which will be hereinafter more tally described and particularly pointed out in the appended claims, reference being bad to the accompanying drawings tlt'orn'iing part of this l specification, and inwhich:

Figure 1 is a view in horizontal section, illustrating the preferred embodiment of the invention; l

Figure 2 isa viewin longitudinal vertical section, taken on line 2 -2 of Figure 1;

Figure 3 is a view in transverse vertical or C(HlhllllflOUSlY Y" sake of illusta-tion is shown the preferred embodiment oi the invention, the numeral l designates the base of the vise which maybe suitably secured to a bench or other support. it fixed jaw, designated generally atilEZ suitably ntlounted on the base and comprises a body portion 13, ashank 14land a jaw face 15 oi hardened steel.

A movable jaw 16 coacts with the fined jaw and includes a hollow slide 1'? arranged in an opening 13 provided in the body pen tion 13 of the fixed jaw and having ribs or guides 18 which slida-bly fit in slideways 19 also provided in the body portion 13 of the fixed jaw. it shank 2G is integrally termed with the slide 17 and. carries a hardened steel j aw face 21.

An operating screw or spindle is rotatably jo-urnaled in a bearing 26 provided therefor in themovable jaw and is provided with a collar 27 positioned to rota-tablyabut a shoulder 28 formed on the movablevj aw and this spindle or operating screw is held against longitudinal. displacement by means oi? a stop plate 30 which is carried by the movable jaw and projects into an annular groove 31 cut or otherwise formed in the operating screw the stop plate being releas ably held in this position by means of a screw or pin 82 (see Figure A nut carrying frame, designated gei'ierally at 35 is assembled with the body portion 13 of the fixed jaw being arranged in the opening 13 thereof, and is provided with upper and lower tongues 36 and 37 respecand provided therefor in the lower part oi the body portion of the fixed jaw. In assemblingthe nut carrying trame with the tired jaw, it is entered through theopeir rear end of the fined jaw, the tongues 36 and 3"? sliding in the grooves 88 and 39 to permit of this assembly. When properly positioned on the fixed jaw the bolts 42 and 413 are threaded home and secured to the not carrying frame in proper position; i The sec-- tions 10 and 41 of the frame are provided with hearing lugs 1-6 and ll" which extend inwardly and which are accommodated in the opening of the hollow slide, it being understood that the slide is not only hollow but also has one wall or face removed to accommodate these bearing lugs. A cover plate 18 is integrally formed with the section 5 1v and extends over to the section ll), the cover plate having a flange 49 whichembraces the adjacent portion of the section 4:0 and this cover plate serves to enclose the mechanism carried by the frame 35 as will hereinafter more fully appear.

A nut, designated generally at 50 is provided and coacts with the operating screw or spindle 25 and this nut is carried by the bearing lugs 46 and 17. The nut 50 comprises two coacting parts or sections, designated at 51 and 52, the part 52 being fitted within the part 51 and each part includes a one-half of the threaded bearing, desig nated at 53. The part 51 of the nut includes upper and lower plates, designated at 51 and 51 and curved end portions 51 and 51 The plates 51 and 51 have lateral extensions 51 and 51 which are slidably received in guideways 46 and 17* provided in the bearing lugs 16 and 47 and in the adjacent structure of the section 10 and n ofthe nut carrying frame, as shown in Figures 1, 2 and 4, these bearing lugs serving in this manner to slidably support the parts of the nut. As shown in the drawings, the upper and lower surfaces of the part 52 slidably engage the upper and lower plates 51 and 51 of the part 51 and the side faces of this part 52 engages the adjacent faces of the bearing lugs whereby the part 52 of the nut is constrained to partake of its proper motions.

Operating mechanism is provided for urging the parts 51 and 52 of the nut into and out of engagement with the operating screw 25 and includes a crank shaft 55 rotatably journaled in the frame and having a pair of cranks 56 engageable with pins 57 carried on the part 51 and a single crank 58 of opposite throw with respect to the cranks 56 and engageable with a slot 59 provided in a link 59 pivotally connected to the part 52 by a pin 60 for imparting motion to this part. As shown in Figure at the link 59 has a depending rib 59 slidably received in. a guide slot 51 formed in the lower plate 51 of'the part 51 of the nut. The curved end portion 51 of the part 51 is also provided with a slot, designated at 51 which is alined with or a continuation of the slot 51 and which permits the link 59 to partake of its proper movements and to be assembled and disassembled. It is obvious that when the crank shaft is turned the cranks 56 impart a rectilinear movement to the part 51 and at the same time the crank 58 being of opposite throw imparts movement in an opposite direction to the part 52.

Actuating mechanism is provided for the crank shaft and preferably comprises a lever 60 pivotally mounted on the frame as by a screw 61 and having fixed thereto a gear 62 which meshes with a gear 63 fixed to the crank shaft. The outer end of the lever is preferably weighted, as at 65, so as to normally move the lever to position to maintain the nut in operative engagement with the operating screw. It is obvious that when the lever 60 is moved its motion will be imparted to the crank shaft by means of the gears 62 and 63 and this motion of the crank shaft will be effective to move the nut into and out of engagement with the operating screw. In the arrangement shown when the lever 60 is moved upwardly, the parts 51 and 52 of the nut will be moved out of engagement with the operating screw and when the lever is moved downwardly or permitted to fall downwardly these parts of the nut will be moved into operative cngagement with the operating screw.

In this manner the jaws of the wrench may be quickly and readily adjusted and at the same time the operating screw may be quickly brought into action in order to impart to the jaws a powerful grippin force. The nut carrying frame may be reac ily disassembled from the body portion of the jaw and action may be readily had to various parts of the nut and of the operating mechanism therefor for purposes of cleaning, replacement and repair.
